Protection
of wells should start during their construction. Wells should be located or
sited on a good site i.e. at the highest point in the proposed site to prevent
entry of polluted underground water into it. It should not be located on a bad
i.e. reclaimed land, it should not be sited near any latrine accommodation, the
distance between a well and any latrine must not be less than 100m apart.

The
interior of the well should be lined with prefabricated concrete rings. This
will prevent the well from collapsing and at the same time discourages the
entry of pollutants into the well.

The
well must be provided with apron of about 1 meter high and the immediate
surroundings of the well must be cemented to drain away water from the well,
channeling this water away from the well forestall waste water from re-entering
the well.

A
water tight cover should be provided to discourage pollutants from gaining
access into the well. To discourage the users from dipping all sorts of unclear
drawing buckets into the well, a pulley should be provided with a clean bucket
attached to it and which must be used by anyone coming to draw water from the
well.

Where
the water is pumped out through mechanical device (pumping machine) all holes or
crevices bored to let pipes into the well should be blocked and plastered. This
is to guide against the entry of rats, lizards, insects into the well. The
storage tank should be washed clean at regular intervals.
